Samples for one analyte
Samples taken for Cyanide across the water systems Mississippi State Department of Health serves — where it was looked for, and at which sampling point.
681–700 of 2,098 samples. From samples collected September 28, 2024 to September 28, 2026. These dates are applied here by default; they are not a limit on what the agency records. Show 5 years, back to September 28, 2021.

This is where it was looked for
Each row is a sample taken for Cyanide. These rows carry no result and no measured amount — a row means the analyte was sampled for at that point, not that it was found there.
Which analytes a system has detected, and when, is on that system’s own sample results page, reachable from its record.
